"He's a badass, a total badass," Roberts tells TVGuide.com with a laugh. "I think he's a visionary. He's got some political clout in the city and is able to collect the best and the brightest from New York's finest and assemble them onto his Major Crimes force. That's how he comes to meet Carrie and Al. And chaos begins immediately."

Roberts is one of a three new faces joining the resurrected series. Tawny Cypress will play Murray, a former decorated FBI agent, while James Liao will play Jay, a detective who specializes in technical subjects.
